This patch makes my AMD fam10 board not work (K8 works). The resource can not be allocated correctly.

Major changes: 1. Separate resource allocation into: A. Read Resources B. Avoid fixed resources (constrain limits) C. Allocate resources D. Set resources
Usage notes: Resources which have IORESOURCE_FIXED set in the flags constrain the placement of other resources. All fixed resources will end up outside (above or below) the allocated resources.
Domains usually start with base = 0 and limit = 2^address_bits - 1.
I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is still there for resources. Some platforms may want to change that, but I didn't want to break anyone's board.
Resources are allocated in a single block for memory and another for I/O. Currently the resource allocator doesn't support holes.

Thanks for testing. I'm sorry it broke. It looks like I forgot to add IORESOURCE_BRIDGE for the fam10 resources, so they get skipped by the allocator.
Could you try this patch?

I tested this patch. The resource can be allocated. But the kernel can not go. After the "Jumping to entry point...", nothing comes out. I don't know the cause. Do you know?

I guess fam10 code allocates a separate register for prefetchable memory. K8 doesn't. Since I didn't add IORESOURCE_BRIDGE to the prefetchable resource, anything prefetchable didn't get allocated (look for ERROR: ... not assigned messages)
Here's an updated patch. Thanks for testing.

The last piece of the patch isn't necessary, but it would be nice to unify the K8 and fam10 code more than they are.

The patch has been tested and passed on fam10 board. I added an acked-by line to it, but I didn't review it. I didn't trace what happened in these patches and don't know what they mean. I just tested it. If it is appropriate,

Since it was a simple patch and it fixed the problem, I'll take it :)
The IORESOURCE_BRIDGE flag helps the allocator know which resources belong to bridges.

Actually, if you think about screen size and grub menu, it is pretty obvious that it is not a bug. Maybe not extremely efficient, but 2000 characters are exactly what fits on a 80x25 screen, so this is nothing but clearing the screen by writing spaces to it.

If the program writing the display does not word-wrap at the edge of the screen then some data just disappears. I'll still call it a bug: there should be a "newline" at the end of the 2000 characters to ensure the data that follows the 2000 characters is on-screen.

Doesn't that depend on the console driver?

The whitespace is caused by "tinycurses" from libpayload. Not sure there is much we can do about it.. If you have a patch to fix the issue it will surely make many people happy.
